The KiwiSDR Waterfall Display

The Waterfall Display is pretty typical of waterfall spectrum displays on many SDR applications.

The current frequency is indicated by an icon on the Frequency Scale Header and displayed numerically on the the top left of the Control Panel.

The main control sets are located on the Control Panel. There are buttons for zooming the waterfall in and out and for frequency tuning along with drop-down menus for band selection and audio and digital decoding modes.

Another nice feature of the Kiwi is that it will remember some of your selections for when you connect again:

• Name/Callsign field entry
• Frequency selected
• Mode button selection
• Waterfall zoom level
• 9/10 kHz LW/MM band step button setting
• Waterfall/Spectrum settings
• Audio settings
• AGC settings
• Noise blanker/noise filter settings

Information and Control Panels
Information Header	Displays general information about the station	It includes the station name, location, the antenna in use and the current time.
DX Label Header	Displays a collection of DX Labels (like bookmarks) each containing a set of saved tuning parameters. When clicked the KiwiSDR tunes to the saved frequency and sets the receiver mode, passband and decoding parameters. If specified it will start an extension as well	DX Labels provide a convenient way to remember and then quickly tune the KiwiSDR to favorite stations.
Frequency Scale	A frequency scale is provided for the waterfall display. The selected frequency is denoted with a trapezoidal frequency icon:	The frequency icon is centered on the currently selected frequency and its width indicates the bandwidth corresponding to the currently selected operating mode. ⓘ KiwiSDR Frequency Tuning
Control Panel	The Control Panel has most of the controls for operating the KiwiSDR including band selection, receiver operating modes and the waterfall display characteristics.	ⓘ KiwiSDR Control Panel
